Description
Technical field
The present invention relates to cordless communication network, particularly relate to the method and apparatus that scheduling in a communication network allows to send signaling.
Background technology
Along with the growth of business demand, the operator of cellular network needs more frequency range except authorizing frequency range (licensedband). LTE in unauthorized frequency range (unlicensedband) disposes (being hereinafter called for short " LTE-U "), typically over 5GHz, it is possible to realize unloading a large number of services from license carrier wave. In 3GPPLTE version 13, the LTE-U research project about unauthorized frequency range has been started up. The first stage of LTE-U includes using unauthorized frequency range as descending supplementary frequency range and use authority frequency range as uplink band. Because LTE-U partly runs on unauthorized band downlink, it must be network coexisted with other, for instance, other LTE-U and Wi-Fi (such as 802.11ac) system.
Concealed terminal is a well-known problem in Wi-Fi system. Fig. 1 illustrates the schematic diagram of the hiding joint terminal interference between Wi-Fi access point. Fig. 1 includes two access point (AP:AccessPoint): AP1 and AP2. Terminal 1 is connected with AP1, and terminal 2 is connected with AP2. AP1 can not hear the transmission coming from AP2, but terminal 2 can hear the transmission of AP1 and AP2. When AP2 transmits data to terminal 2, AP1 can not sense the transmission of AP2, and likely transmits data to terminal 1, this creates the terminal the interference to terminal 2.
For this, Wi-Fi introduces csma/collision detection (CSMA/CA:CarrierSenseMultipleAccess/CollisionDetect) mechanism to eliminate hidden terminal problem. Fig. 2 illustrates the schematic diagram of the CSMA/CA mechanism for avoiding the concealed terminal between Wi-Fi access point to disturb. As in figure 2 it is shown, AP2 first sent signaling (RTS:RequesttoSend) to terminal 2 transmission request before transmitting any business datum. The terminal of any RTS of detecting can stop transmission. For response RTS, terminal 2 meeting sense channel, if channel is idle, then replys to AP2 and allow to send signaling (CTS:CleartoSend).Similarly, stopping is transmitted by any other-end being able to detect that this CTS. In fig. 2, once AP1 detects CTS and transmits data thus without to terminal 1. And when AP2 receives the CTS coming from terminal 2, to terminal 2 transport service data. In this way, terminal 2 avoids the interference being subject to coming from AP1.
LTE-U can also adopt CSMA/CA mechanism to solve the coexistence problems between LTE-U and between LTE-U and Wi-Fi. But, the operation way of LTE-U and Wi-Fi is different. Wi-Fi adopts the transmission mode based on competition, that is, the not scheduled channel taking the free time of terminal. In contrast, in LTE-U, then carried out scheduling resource by base station. Because the mode more likely of LTE-U is to use unauthorized frequency range as band downlink, subscriber equipment the CTS sent to base station is authorizing transmission in frequency range. How effectively scheduling is a urgent problem for transmitting the resource of CTS.

Detailed description of the invention
In the specific descriptions of following preferred embodiment, reference is constituted the accompanying drawing appended by the part of the present invention. Appended accompanying drawing has been illustrated by way of example and has been capable of specific embodiment. The embodiment of example is not intended as the limit all embodiments according to the present invention. It should be noted that, although accompanying drawing describes the step of method in the present invention with particular order, must according to this particular order to perform these operations but this does not require that or implies, or the operation shown in having to carry out all could realize desired result, on the contrary, step described herein can change execution sequence. Additionally or alternatively, it is convenient to omit some step, multiple steps are merged into a step and performs, and/or a step is decomposed into the execution of multiple step.
The present invention and embodiment mainly describe the non-limiting embodiment for specifically exemplary network configuration and deployment relevant with 3GPP specification. Particularly LTE communication system is illustrated as non-limiting example the suitability of described embodiment. Therefore, the description of given in the text exemplary embodiment refers specifically to directly related term. This term only for the content of non-limiting example, does not limit the present invention in any way naturally yet. On the contrary, as long as meeting features described herein, it is possible to use other any network configuration or system deployment etc.
The central scope of the present invention there are provided the scheme of a kind of scheduling CTS at communication network. The program includes: base station is used for RTS, the CTS schedule information indicating CTS schedule information for indicating subscriber equipment to transmit CTS in uplink authorization frequency range to respond RTS to user device transmissions in unauthorized frequency range.
Base station in the present invention can be LTE-U base station, it is also possible to be any base station using unauthorized frequency range. Corresponding to LTE-U base station, subscriber equipment should also be as being a LTE-U subscriber equipment. In the as explained below of the present invention, " subscriber equipment " represents the subscriber equipment being under the jurisdiction of LTE-U, and " terminal " represents the terminal unit being under the jurisdiction of Wi-Fi access point.
Although it will be understood by those skilled in the art that and for LTE-U base station and network, technical scheme be described below in an example, but the solution of the present invention also apply be applicable to the base station in other networks and subscriber equipment.
In one embodiment of the invention, base station is used for indicating the RTS of CTS schedule information to user device transmissions in unauthorized frequency range, CTS schedule information in this RTS can explicitly include subscriber equipment for transmitting time resource and the frequency resource of CTS, it is possible to adopts the form of the Physical Downlink Control Channel (EPDCCH:EnhancedPDCCH) of Physical Downlink Control Channel (PDCCH:PhysicalDownlinkControlChannel) or enhancing.Such as, CTS schedule information can be DCI format 0, and contains time resource and frequency resource in this DCI format 0.
Preferably, the CTS schedule information in this RTS may also include subframe indicator, and this subframe indicator is for indicating subscriber equipment to transmit CTS in the subframe indicated by subframe indicator. Such as, include subframe indicator k in CTS schedule information, subscriber equipment kth subframe after receiving the rts is transmitted CTS. Such as, k=6, transmits CTS in subscriber equipment the 6th subframe after receiving the rts. The CTS of such different user devices is distributed in different subframes in the time domain to avoid conflict and to provide motility.
If the CTS schedule information in RTS does not include subframe indicator, then subscriber equipment can transmit CTS in predefined subframe to base station. Generally, according to the process time of subscriber equipment and up-downgoing channel configuration etc., as an example, k=4.
In another embodiment of the present invention, preposition RTS can be adopted implicitly to indicate the ensuing CTS schedule information of user equipment searches. Base station first sends a preposition RTS to subscriber equipment, the form of this preposition RTS can be identical with the RTS form in Wi-Fi code, and this preposition RTS adopts such as PDCCH or EPDCCH form the RTS comprising CTS schedule information for implicitly instruction user equipment searches. Such as, CTS schedule information can be DCI format 0, and contains time resource and frequency resource in this DCI format 0. Can comprising such as CTS-RNTI (RNTI:RadioNetworkTemporaryIdentify) information in this RTS, this CTS-RNTI information decodes the CTS schedule information in this RTS for subscriber equipment in PDCCH/EPDCCH search volume. Such as, subscriber equipment is preconfigured CTS-RNTI, base station send RTS time standby CTS-RNTI as mask, subscriber equipment attempts to receive after the RTS of mask at PDCCH or EPDCCH, the RTS that blind solution (blinddecoding) receives is removed, thus greatly reducing the number of times of blind solution with CTS-RNTI.
In above-mentioned implicit aspect, if preposition RTS not including for indicating when subscriber equipment is searching for described RTS subframe indicator, preposition RTS be additionally operable to instruction subscriber equipment with the preposition RTS predefined subframe being associated in search RTS.
In above-mentioned implicit aspect, preposition RTS may also include the second subframe indicator, this second subframe indicator for indicate subscriber equipment search in the subframe indicated by the second subframe indicator described in comprise CTS schedule information RTS. Such as, including the second subframe indicator k2 at preposition RTS, subscriber equipment receives RTS in 2 subframes of the kth received after preposition RTS. Such as, k2=0, subscriber equipment receives RTS in the identical subframe receive preposition RTS. Again such as, k2=2, the subscriber equipment the 2nd subframe after receiving preposition RTS receives RTS.
In yet another embodiment of the present invention, base station sends RTS to subscriber equipment, and the form of this RTS can be identical with the RTS form in Wi-Fi code. Base station implicitly indicates frequency resource and the time resource of user device transmissions CTS for the Radio Resource transmitting this RTS. That is, base station is associated in the running time-frequency resource of the CTS of this RTS for transmission response for the resource and subscriber equipment transmitting this RTS. Such as, this RTS can take some resources in unauthorized frequency range, and the index of these some resources as the input of a function, and can calculate the index of Physical Resource Block for transmitting CTS with this function.This function pre-configured can also inform the user that equipment by suitable signaling.
In one embodiment of the invention, the instruction indicating the one or more CTS of described user device transmissions can be included in the rts.
In one embodiment of the invention, CTS schedule information in the rts may indicate that and not include CTS schedule information in described RTS. Such as, when only unauthorized frequency range is not without mandate frequency range (such as having uplink authorization frequency range), or authorize frequency range owing to, when such as load too high is temporarily unavailable, avoiding the need for including in the rts running time-frequency resource. So, CTS schedule information in the rts indicates in described RTS and does not include CTS schedule information.
In one embodiment of the invention, after receiving the RTS coming from base station or preposition RTS and RTS, subscriber equipment can according to the instruction in RTS or preposition RTS, and row shares transmission CTS in channel or Physical Uplink Control Channel physically.
In one embodiment of the invention, after receiving the RTS coming from base station or preposition RTS and RTS, according to the instruction in RTS or preposition RTS, subscriber equipment can transmit one or more CTS. Such as, subscriber equipment transmits CTS in the scheduling resource authorizing frequency range and transmits another CTS in unauthorized frequency range, in unauthorized frequency range, the CTS of transmission can be different for such as Wi-Fi access point or the base station in the unauthorized frequency range of uplink and downlink with Wi-Fi function, the CTS transmitted in authorizing frequency range and the CTS form transmitted in unauthorized frequency range.
Fig. 3 illustrates the schematic diagram of the user device transmissions CTS between Wi-Fi access point according to an embodiment of the invention and LTE-U base station.
As it is shown on figure 3, subscriber equipment 1 is within the coverage of Wi-FiAP1 and LTE base station 1. But terminal 1 is not in the coverage of AP1 in the coverage of base station 1.
Base station 1 is expected to unauthorized frequency range and sends business datum to subscriber equipment 1. When base station 1 listens to unauthorized frequency range for time idle, base station 1 sends RTS to subscriber equipment 1. This RTS class comprises such as DCI format 0, and this DCI format 0 comprises subscriber equipment in the schedule information authorizing band transmissions CTS.
In such as the 4th subframe after subscriber equipment 1 receives RTS, subscriber equipment 1 transmits encoded CTS to base station 1 in the scheduled such as Physical Uplink Shared Channel authorizing frequency range. Meanwhile, subscriber equipment 1 also can transmit CTS to AP1 in free frequency range.
Once base station 1 receives the CTS coming from subscriber equipment 1, base station 1 starts to send downlink service data to subscriber equipment 1. Once AP1 receives the CTS, the AP1 that come from subscriber equipment 1 and does not send any downlink data to terminal 1.
Fig. 4 illustrates the device schematic diagram of the scheduling CTS at communication network according to an embodiment of the invention. Device 400 in Fig. 4 can in the such as base station of communication network. Device 400 includes the first transmission unit 410, it for being used for indicating the request of CTS schedule information to send signaling (RTS) to user device transmissions in unauthorized frequency range, and this CTS schedule information sends signaling (CTS) to respond RTS for indicating subscriber equipment to send permission in uplink authorization frequency range; And first receive unit 420, its in described mandate frequency range receive come from described subscriber equipment described allow transmission signaling. CTS schedule information in device 400 can explicitly include described subscriber equipment for transmitting time resource and the frequency resource of described CTS.
